How to scrape Google Ads data

Hey guys,

Google Ads scraping looks simple until you actually try to track a competitor's campaign for more than a day.

Rate limits, shifting page structure, and Google's own blocking rules make this hard on the technical side. Most guides stop right there.

Ad rotation causes most of the confusion. A single pull only shows whatever combination happened to be live at that exact moment. Query, region, and device all shift what you see too.

Track messaging over time and you need repeated checks under the same query, region, and device, run on a schedule. You also need a way to tell an ad that disappeared apart from a page that just failed to load.

Anyone here already doing this? Checking competitor ads by hand, or did you build something to automate it?
